Investigation of thermal characteristics of Strontium Chloride composite sorbent for sorption refrigeration
Thermal Science and Engineering Progress, 2019Co-Authors: Ke Tang, Long Jiang, Liwei Wang, Yaodong Wang, Anthony Paul RoskillyAbstract:Abstract Thermal characteristics such as thermal conductivity, permeability, and sorption kinetics, which determines the overall sorbent performance, play as the critical roles in the sorption refrigeration system. In this paper, composite Strontium Chloride (SrCl2) developed with a host matrix of Expanded Natural Graphite (ENG) has been comprehensively investigated under different densities and mass ratios of salt. Results indicate that the composite sorbent has overall good heat and mass transfer performance. The highest thermal conductivity is 3.07 W/(m.K), which is 15 times higher than normal granular SrCl2. The permeability of composite sorbent ranges from 9.5 × 10−10 to 9.36 × 10−14 m2. Sorption performance of composite SrCl2 has also been tested, and the results showed that for the sorption amount ranged between 400 and 700 (g/kg SrCl2) ammonia at 40 min in the adsorption process. These quantitative results obtained from this study can be used as crucial parameters to conduct the simulation modelling for the SrCl2-ENG sorption system.

Investigation on innovative thermal conductive composite Strontium Chloride for ammonia sorption refrigeration
International Journal of Refrigeration, 2018Co-Authors: Long Jiang, Ruzhu Wang, Anthony Paul Roskilly, L.w. Wang, Ke TangAbstract:Abstract A novel composite Strontium Chloride (SrCl2) is developed with porous material of expanded natural graphite (ENG) and nanoparticle of carbon coated nickel (Ni@C) as the additives. Thermo-physical properties such as thermal diffusivity, thermal conductivity and permeability are investigated and analyzed. The highest thermal diffusivity could reach 6.2 mm2⋅s−1. Correspondingly the highest thermal conductivity is 4.03 W ⋅ m−1 ⋅ K−1, which is about 20 times higher than that of granular SrCl2. Permeability of novel composite SrCl2 ranges from 1.31 × 10−9 m2 to 1.07 × 10−13 m2. Moreover, samples with Ni@C have better sorption performance in ammonia than those without Ni@C due to the improved heat and mass transfer performance. Ammonia sorption quantities of novel composite SrCl2 range from 0.39 kg⋅kg−1 to 0.67 kg⋅kg−1 when evaporation temperature varies from −15 °C to 15 °C. The addition of ENG and Ni@C shows great potentials for sorption refrigeration by adjusting the concentration swing.

Applied Thermal Engineering, 2017Co-Authors: Long Jiang, Ruzhu Wang, Anthony Paul Roskilly, Ke Tang, Yaodong Wang, Liwei WangAbstract:Abstract A novel composite Strontium Chloride (SrCl 2 ) is developed with porous material of expanded natural graphite (ENG) and nanoparticle of carbon coated aluminum (Al@C) as the additives. Samples with different densities and mass ratios of salt are produced and classified into disk and plate types which are parallel and perpendicular to the compression direction, respectively. Thermal conductivity is investigated by laser flash measuring method whereas permeability is tested through Ergun model. It is indicated that with regard to thermal conductivity and permeability, plate samples show the better performance than that of disk samples. The highest thermal diffusivity could reach 5.7 mm 2 ·s −1 when the density is 800 kg·m −3 . Correspondingly the highest thermal conductivity is 2.96 W·m −1 ·K −1 , which is about 15 times higher than that of ordinary granular SrCl 2 . Permeability of plate and disk samples range from 9.9 × 10 −10 m 2 to 9.89 × 10 −14 m 2 and 2.91 × 10 −10 m 2 to 2.46 × 10 −14 m 2 when the density ranges between 400 kg·m −3 and 600 kg·m −3 . The possible applications are presented and compared by using heat and mass properties of novel composite SrCl 2 , which show their respective advantages when simulating the performance for the different reactors.

Modeling of Strontium Chloride hexahydrate growth during unseeded batch cooling crystallization by two-dimensional population balance equation
CrystEngComm, 2015Co-Authors: Yuanyuan Qian, Yuzhu Sun, Xingfu SongAbstract:In this study, the growth of Strontium Chloride hexahydrate during unseeded batch cooling crystallization was investigated and modeled by the two-dimensional population balance equation. The results suggested that in a well-mixed crystallizer, no obvious agglomeration and breakage were observed. The initial supersaturation and cooling rate were the key factors of crystal growth and the crystals grew following a size dependent mechanism. Thus, the growth of SrCl2·6H2O was modeled as a function of supersaturation, temperature, and crystal size. The calculated crystal size and size distribution showed good agreement with the experimental values, proving that the model could well predict the growth behavior of SrCl2·6H2O in the system. This study not only fills the research vacancy of SrCl2·6H2O crystallization, but also contributes to the optimal design of the crystallization process, aiming at preparing SrCl2·6H2O crystals with a larger size and a narrower size distribution.

preparation of Strontium Chloride hexahydrate by batch cooling crystallization control of crystal size and morphology
Crystal Research and Technology, 2014Co-Authors: Yuanyuan Qian, Yuzhu Sun, Xingfu SongAbstract:The effects of initial supersaturation, cooling rate, and stirring rate on the morphology of Strontium Chloride hexahydrate (SrCl2·6H2O) crystals were investigated by batch-cooling crystallization, providing optimal operating conditions. Uniform needle-like crystals with a length of 1200.50 μm and a width of 100.92 μm on average were obtained. The corresponding aspect ratio of length to width was about 11.90. Moreover, the morphological modification of SrCl2·6H2O crystals using cetyltrimethylammonium Chloride (CTAC) was studied. When 20.30 mmol·L−1 of CTAC was added, the length and width of crystals were 792.71 μm and 233.25 μm, respectively, and the corresponding aspect ratio decreased to 3.40. The shape of SrCl2·6H2O crystal changed to granule-like, probably because of the strong interaction of CTAC with the SrCl2·6H2O facets with a denser distribution of Cl− ions. This study offers a simple, flexible, and highly efficient approach to regulate the morphology of SrCl2·6H2O crystals and opportunities for multiple applications of SrCl2·6H2O.
